Keith's bandmates in The Prodigy released an official statement about his death, saying 'he will be forever missed'

An employee is believed to have found Keith’s body at the £1.5million marital home in Dunmow, Essex. He ran 5k in Chelmsford on Saturday morning but pals feared he had slipped back to his hedonistic ways.

Footage also emerged showing him appearing to black out before being held up by security guards at the Prodigy’s last-known UK gig in Brighton last November.

Fan Kenneth Edwards, 52, said it looked like he was “on some sort of drugs”, adding: “I’ve been to a lot of his concerts and not seen that before. It was shocking to see.”

A fellow diner at the Galvin Green Man in Chelmsford, Essex, told the website: "My wife and I were dining on an opposite table when my baby son threw a fork on the floor, which Keith picked up and said hello, cracking a joke with my wife about it.

"He seemed really happy, talking to his trainer about how he’d achieved a personal best running and how it made him feel much better, opening his lungs up."

The diner added: "There was no one else in the pub for him to be putting on an act for. So I was surprised and gutted as a fan of his work when I heard that he’d taken his own life so soon afterwards."

The singer was discovered at around 8am on Monday after police and paramedics were called to his home in Dunmow, Essex.
